Heat the olive oil in a heavy-bottomed pot over medium heat.
Add the ground turkey and cook until browned, using a spatula to break the meat into small crumbles.
Toss in the diced red onion and bell pepper, cooking for 5 minutes until the onion is translucent and fragrant.
Stir in the chili powder, cumin, garlic powder, sea salt, and black pepper to coat the turkey and vegetables.
Pour in the kidney beans, tomato puree, and water, then stir to combine all ingredients.
Bring the chili to a light simmer, then cover and cook for 15-20 minutes until the liquid has thickened into a rich sauce.
Ladle the chili into a bowl and enjoy while hot.
